Flags with Triangles & Chevrons
Equilateral or isosceles triangles extending from the hoist edge over horizontal stripes, led by the revolutionary twin flags of Cuba and Puerto Rico.
Construction & geometry note: An equilateral triangle on a 3:5 flag reaches 51.96% of the hoist height along the horizontal axis, while on a 1:2 flag it reaches 43.3% of the total fly length.
